Claper

Claper is an open-source audience engagement platform that makes presentations interactive with real-time participation. It helps speakers collect live feedback while giving attendees an easy way to ask questions and respond during talks.

Key Features

• Live audience interactions such as polls, quizzes, and Q&A during an event
• Real-time feedback to help presenters adapt content while speaking
• Event reporting and data exports for post-event review
• Team collaboration to manage presentations and events together
• Multi-language user interface (includes English, French, German, Spanish, Dutch, Italian, Hungarian, and Latvian)

Use Cases

• Classroom engagement with quick quizzes and anonymous questions
• Corporate meetings to gather input and validate decisions via instant polls
• Conferences and live events to run interactive sessions and collect feedback

Limitations and Considerations

• Some hosted-plan features and limits (such as attendee caps and presentation size) may differ from a self-managed deployment

Claper is well-suited for educators, teams, and event organizers who want a lightweight, real-time interaction layer for presentations. It provides core engagement workflows while remaining deployable on your own infrastructure.
